SPEEDOMETERSPEEDOMETER INSPECTION (ON−VEHICLE)(a) Using a speedometer tester, inspect the speedometer

for allowable indication error and check the operation ofthe odometer.

HINT: Tire wear and tire over or under inflation willincrease the indication error.If error is excessive, replace the speedometer.(b) Check the speedometer for pointer vibration and

abnormal noise.HINT: Pointer vibration can be caused by a loosespeedometer cable.

NO. 1 VEHICLE SPEED SENSORNO. 1 VEHICLE SPEED SENSOR INSPECTIONCheck that there is continuity between terminals A andB four times per each revolution of the speedometershaft.If operation is not as specified, replace the speedometer.
